Use this online sky map to view the stars and constellations that will be visible tonight where you
live. On the star map, click the city and state link that appears at the top center of the map. In the menu
that appears, type your current city and state into the location field and press Go! Then click the tab
labeled Time in the menu above the map. Use today's date but insert a time of 22:00 (10:00 p. m.).
The circle on the screen filled with stars and constellations represents the hemisphere above the
observer in your location on Earth. The zenith, the point directly overhead, is in the center of the circle.
The perimeter of the circle is where the sky meets the horizon. Zoom in and maneuver the map until
you've located the constellation Ursa Minor, which is also known as the Little Dipper. Zoom in on Ursa
Minor until you can clearly see all seven of its stars.
Draw and connect the stars of Ursa Minor and label the star Polaris.
